RAIL-STAY.

Patented Dee. 5, w11.

To all whom it muy concern:

Be it known that l, Louis ilANsoN, a citi -f zen of the United States, residingr at liar-ine.

in the county ot' ltacin and State of visron-m, have invented certain new and useful lmprovelnf its' in` llail-'hta \s, of which the following is a specilcation.

.\l\.' intention relates to devices knmvn a. rail tays, rail anchors, or anti-Creepers. and the invention has for itsA object lo provide a rail stay, anchor, or antiwreeper having certain'uovel and in'iproverl features ot coustrmtion to he hereinafter more fully de- Mlllvetl.

primary amlspeeiie object of the in- 'venion is to provide. in a rail stay comprisin e; two parts or elements which are given a relative movement with respect to ca eh other when the device is driven orotber-rise caused lo gril: lhew'rail.;meansl of novel character for locking said parts or elements haring said relativ: movement. so to positiwly prevent any reiersc movement between saill parts. thereby prewning the grip of the device on the rail from becoming loosened llne to the vibration of the rail or nher causes.

The invent ion is illustrated, in a preferred embodiment, in the accompanying drawing, in which- Figure l is a plan rien' showing the rail stay applied to a rail; Vig. 9, a sectional eleration taken on line 2--2 of Fig. l; Figs, 3 and 'l, .sectional views taken on line 3--3 of Fig. 1, Fig. -,l1o\re\'er, showing the wedge in the position which 1t takes before it is driven into the clamping position shown in the other figures.

Like characters of reference indicate like parts in the several figures of the drawing.

Referring to the drawing. A represents a T section railway rail of ordinary character and B one of the cross ties on which the rail is laid.

The form of ant-i-creeper or rail stay in tonnection with which the features of con- :truction constituting my invention are hown consists of a bar C, preferably of nalleable iron, formed at one end with the ntegral hook or jaw D a'nd at the other nd with the integral jaw E and tie abut,-

ient F which latter projects from the bar Yat substantially right angles and is formed ith the ange f, the outer surface of which preferably curved and bears against the de of tie B; the rail stay comprising further a wedge element G which is adapted to bc. driven into the jaw E, which is preferahlv apercd in conformity to the taper of the wedge, and against the oase of rail A. Preferably the bottom of the jaw E is formed with a recess r* in which the wedge :et and by preference the Wedge formed with a `roc/ve (i which receives the edge of the mil base. The jaw i is formed with'a projection i'l, the under surface of which is formed with one or more teeth ,T which are adapted to engage with the oppositely inclined teeth K formed on the upper surface of wedge G. The bar C- is preferably strenthened by the strengthening web L which is prolonged so as to extend around the inw E where its width is preferably increased as indicated at L. The purpose of this to give rigidity to the jaw. The projection ll is preferably reinforced by a web a which tapers (lc-.rn toward the extremity of the projection. While the jaw E is intended to be as rigid as possible the projection is designed to be capable of slight, 'lispiaccment.. For this reason its strenghening rib H is tapered down toward the extremity of the projection which allows the projection tri bend slightly.

'hile 'malleable iron, of which the device is preferably constructed, does not have a great deal of elasticity, it is possible, with the construction shown, to obtain elasticity enough to carry out the purpose of my invention.

Preferably the projection J dips down a trifle at its extremity so that it stands in the path of tbe wedge as indicated in Fig. 4. The driving in of the wedge forces the projection up to the position best shown in Fig. 3. lf it should happen that the projection, either by faulty casting or subseqt ent rough handling of the device, he tound to stand so far away from the Wedge that a close en gagement does not take place between the teeth J and K it can easily be hammered down upon the Wedge so as to provide such engagement. In fact, it desired, the device could with intention, be constructed so as to operate in this manner. It. will be noted that the projection H is so placed that any rough handling that the casting may receive will he lil-rely, if affecting the projection at all, to bend it downwardly or inwardly. This will do no harm because it is forced back by the driving of the wedge.

e b, wwe@ I am aware that it has been proposed to use cci-engaging teeth or serrations for the purpose of locking together the parts of a rail stay, but so far asl am aware the constructions and arrangements which have heretofore been devised are either impractical or vvery undesirable. It has been proposed, for example, to use a spring tooth in connection with the rack but this is nndesirable beca/usc a spring element has little strength and at best is very4 liable to break. Rail stays have also been devised involving Vthe use ot interlocking teeth in which the stay is constructed with 'loosejoints so as to allow the teeth to come into engagrzement.V Structures of this sort are undesirable-bel. cause the loose joints cannot. .tand the great strains put npon a rail stay and because 'the looseness of the parts which are in this manner attempted to be locked together militates againstthe positivencss of the`- lock. there the stapv comprises two parts which have to be forced or driven into an engaging position by being moved one over the other and which, in order to make the stay effectively grip theY tie have to be sub stantially rigid and eventually assume a,

close engagement as, for .,i-nnple, where there is a Wedge action between the parts.

the provision of the surfaces of contact of said parts that are designed to come into the close engagement with coacting vteeth defeats and prevents the intimacyt'ot' contact. between the parts necessaryarfor the e`ectivencss of the clamp, because,- aas. willl be evident; the intermediate positions ot the parts While one set of teeth is riding over the other set` will involve a closer Contact between the pai-rs than the subsequent positions in which the teeth are engaged. The alternative is that the drivingizi of the wedge will plane oit the teeth and so destroy the intended lock. It will be seen 'that in the comtruction herein shown the arrangement et one set of teeth on a slightly tier- -ible projection from one of the. rigid coengaging elements of the stay, co-Wit, the

jaw E. permits a close engagement between the teeth without affecting the intimacy of contact between the jaw and the wedge which is driven int-o 'the jaw. In other words, one set of locking teeth is formedon a partA which is not subjected and does not have to be subjected to the clamping strains between the elements forming the stay, and

' which does not have to be rigid in order -to malte the clamp of the stay or: the rail effective.' f

'Wl'iile have shown this device for preventing reverse movement between the partsl of a rail stay in connection with a stay consis'ing of a bar haring integral jaws at opposite en .dsand of a Wedge which is driven between the rail base and one of said jaws,

it u'ill be obyious that it might be applied.

to staysscitnewhat dierent in structure and makeup,`1 Furthermore, even with the 'rail stay or the sort shown the disposition and arrangement of the parts might be Taried somewhat Without departure from my invention. Therefore I do not limit myself to the particulars shown and described except so far as the same are made. specifically limitations on certain of the claims herein.

l hareused the word teeth to denote the forms designated J and K in the drawing, but it will be understood that the term embracesany sort of serrations or other formations adapted to provide an engagen'ent preventing or resisting the retrograde movement of one part or element of the stay with. respect to the other; also that instead of having two sets of teeth as described the lock mightbe eiected b' a single` 'tooth Working on a succession o teeth,

I claim: s 1. A rail stay comprising two elements which together embrace the base of the rail one of which is adapted to be moved while irr close contact with the other into a rigid relationship therewith, and one of' which comprises a member adapted to bear against the other element and which is susceptible of slight displacement with respect to the rest ot the element ot which it forms a part without affecting the rigid engagement between said elements, said member and the 'portion of the element against which it bears being formed with co-engaging teeth.
